Abstract
An articulating rotary cutting tool configured to articulate a distal cutting tip upon a trigger being operated. The trigger can be locked into various articulating positions. The velocity of rotation of a cutting bit is substantially constant in both articulating and non-articulating positions. An articulation joint is one of a hex ball joint or a flexible spring joint. A button is included to release a locking pressure holding the trigger in a locked position. The trigger may employ articulating sliding surfaces that provide constraint to a flexed head in both directions of articulation.
